Checked on the status of my check at CSC last night, and things are looking better. Here are the details:
N-400 mailed to CSC: 8-20-07
N-400 received at CSC: 8-21-07
Check cashed: 10-29-07
Receipt date: waiting
Given that I mailed in mid-August and my check was cashed in late October, while others here mailed in early October and got their checks cashed one week after mine was cashed, I would say we have some pretty good velocity at CSC (my opinion only). For those of you at CSC who just got their checks cashed, please keep us all apprised as to when you receive your receipts from USCIS. Hopefully, it should be soon even though the website, as of last week, still indicated early August.
